“…However, in previous studies lack of data did not allow subdivision into all categories of PIH. The result in the present study that small newborn size was associated with AP is also consistent with earlier studies (18,19).…”

Objective: To investigate newborns' sizes associated with abruptio placentae (AP) and to assess the association of a history of pregnancy induced hypertension (PIH) and low birth weight with the occurrence of AP and vice versa. Design: A cohort study based on the Medical Birth Registry of Norway. Results: AP in the first birth was associated with higher rates of AP, small for gestational age (SGA), and PIH in the second pregnancy. This was particularly evident for early onset preeclampsia (unadjusted odds ratio: 5.9; 95% confidence interval: 3.0-11.5). PIH in the first pregnancy was associated with higher rates of AP in the second. In women who delivered a newborn with weight below the 5 th birth weight percentile, AP was 2-3 times more likely to occur than with birth weight percentiles 10-89.9. The occurrence of AP in the second pregnancy also increased with decreasing size at birth in the previous. Conclusions: A pregnancy subsequent to AP must be considered a risk pregnancy in terms of recurrent AP and excess risk of fetal growth restriction and PIH. In sibships with PIH, fetal growth restriction, or PA among siblings, the risk of AP is increased. This suggests a shared recurrent etiologic factor involving an abnormal feto-maternal relationship in AP, PIH, and fetal growth restriction.

“…4 Maternal hypertension especially preeclampsia and eclampsia are major risk factors for abruption placenta. 3,5,8,10 Patients with severe preeclampsia have been reported to have a relative risk of 3.8 and those with chronic hypertension with superimposed preeclampsia have a relative risk of 2.8 for placental abruption. 5 In a study conducted by Baha M Sibai et al 11 in 1984 on 303 preeclampsia women, abruptio placentaee was noted in 5.6% women.…”

“…One major antenatal complication of preeclampsia is abruptio placentae, which has serious implication on the health of both the mother and the foetus, which may result in maternal as well as perinatal mortality. 2,3 Abruptio placentae is defined as the separation of placenta from its implantation site before birth of the foetus. The initial event in abruptio placentae is bleeding into the decidua basalis.…”

“…Abruption severe enough to cause foetal death occurs approximately in 1 in 100 deliveries. 1,3,9 Preeclampsia, gestational hypertension, chronic hypertension all is associated with abruptio placentae. The association of preeclampsia in abruptio placentae varies from 10-50%.…”

BACKGROUNDPreeclampsia is a pregnancy specific disorder commonly defined as de novo hypertension and proteinuria after 20 weeks of gestational age. It occurs in 3-5% of pregnancies and is still a major cause of both foetal and maternal morbidity and mortality worldwide. One of the most serious and dreaded complication of preeclampsia is abruptio placentae. Placental separation from its implantation site before delivery of the foetus has been called abruption placentae or accidental haemorrhage. Various studies have shown that there is 2-2.5 fold increase in incidence of abruption in hypertensive disorder of pregnancy.The aim of the study is to study the incidence of abruptio placentae in women with preeclampsia.
